2.9.3 Asynchronous Edge Detection
When the asynchronous edge detection is enabled (without debouncer) and the system is in the Standby Sleep mode, only the first edge will generate an event. The edges following the first edge of the waveform do not generate events until the system wakes up.
Work Around
Asynchronous edge detection does not work; instead use the synchronous edge detection
(ASYNCH.ASYNCH[x]=0). To reduce power consumption when using
synchronous edge detection, either set the GCLK_EIC frequency as low as possible or
select the 32KHz_LPCLK clock (EIC CTRLA.CKSEL=1).
